I picked up a set of 84 Z28 Wheels (15" Alloys), for my '60 Impala recently, and now that I'm going to put them on, I find I need the correct lug nuts. Problem is, according to the Napa catalog, the 84 used a metric lug bolt! I've seen these wheels on a few old cars, was just wondering if anyone here has used them, and how the dealt with this problem? Seem my options are: change the studs to metric (but will the metric shank fit the SAE holes) or find SAE nuts that will work with these wheels. Any info would be appreciated. Thanks.

Do you know for sure the Camaro rims fit your Impala? I am just asking because the Camaro bolt pattern will be 5 on 4 3/4 while the Impala, being a big car, may have the 5 on 5...

IT won't matter a lot the studs are slightly different is size as long as they fit. The taper on the lugnut centers the wheel. Get a lugnut that will fit the threads and make sure the lug taper sit's in the hole.

Big cars didn't get the 5x5" pattern until '71. '60 is 5x4-3/4".

Make sure the lug nut bevel angle is correct. I think some of the Gen3 Camaro wheels used a different angle from "regular".

I think the seat (taper) you are looking for is called conical. Contact Summit or Jegs, they should be readily available.
